Kassa is a fully custodial wallet built around USDT, USDC and Bitcoin — engineered so you never lose funds to a leaked seed phrase, a malicious approval, or a corrupted ledger.
New · Full wallet control from Telegram — instant deposit alertsTrusted by 40,000+ active users worldwide.
Most losses in DeFi aren’t hacks of the chain — they’re leaked keys, blind signatures and unlimited approvals. Kassa’s custodial design closes those doors.
Funds are secured in institutional custody. There’s no private key or 12-word seed that can be phished, screenshotted or lost.
You never sign open-ended token approvals that drain a wallet later. Every movement is an explicit, reviewed instruction.
A focused architecture around USDT (TRC20), USDC (ERC20) and BTC — the assets that matter, done exceptionally well.
Your holdings stay private. Balances and activity are visible only to you and the accounts you authorise.
Every withdrawal is authorised with a passkey and screened before it’s broadcast on-chain — a human-proof safety layer.
Put assets to work with fixed-term locking and transparent rewards, credited automatically at maturity.
Lock part of your balance, unlock stablecoin cash the same moment, and pay it back in easy monthly parts. When you’re done, the crypto you locked is yours again — untouched.
Set aside part of your balance as a guarantee. It stays yours — and even earns a small monthly yield while it’s locked.
Stablecoin lands in your balance the moment your request is funded. No selling, no waiting, no paperwork.
Spread it over 12 easy months. Payments are collected automatically — there’s nothing to remember.
Pay early or right on schedule — the crypto you locked comes back to you in full.
Borrow against what you already hold instead of selling it. You choose the monthly cost you’re comfortable with, and the best offers fill you first.
Put idle stablecoins to work and earn a monthly return as borrowers repay. Your funds are reserved only while lending and free the moment you cancel.
In open DeFi, a corrupted ledger or a single careless signature can empty an account. Kassa’s custodial model keeps you structurally out of harm’s way.
Link your account once with a single-use code and manage Kassa straight from Telegram — balances, wallets, QR deposit addresses, activity and sub-accounts, with an instant alert the moment funds arrive.
Kassa isn’t a public on-chain wallet. There’s no address to scan and no balance to look up — your holdings simply aren’t discoverable, and your transfers leave no public trail.
Register with your email, verify it, and secure your 12-word recovery key.
Get a deposit address for USDT, USDC or BTC. Incoming funds are credited automatically.
Withdraw with a passkey, lock for rewards, or manage sub-accounts — all from one dashboard.
